Abstract

The single crystal structure of carbonyl dicyanide was determined via in situ crystallization. Hirshfeld analysis reveals a dominant interaction between the nitrogen atoms and the electron-deficient carbon framework. The ¹³C NMR spectrum shows resonances at 140.4 ppm (CO) and 110.5 ppm (CN), respectively, with ¹J_CC coupling between the carbonyl and cyanide C-atoms at 100 Hz. The ¹⁵N NMR spectrum shows a resonance at 269 ppm.
